Is the multiplayer scene growing or shrinking? Do we have any numbers on this?

I sometimes worry that more and more people are leaving the game. The amount of inactive 2k voobly accounts is sad, and old pros that don't play anymore, and many people on HD that I used to see a lot that I don't see anymore.

But I could easily be imagining it. There's tons of pro streams with thousands of viewers daily, and 100+ lobbies each on both HD and voobly anytime I check.

But are there any hard numbers to be sure?
